To (LZZ whom it may concern:

Be it known that I, DAVID HILL, a citizen of the United States, residing at Washington, in the county of Beaufort and State of North Carolina, have invented certain new and useful Improvements in Oar-Ventilating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate one form in which I have contemplated embodying my invention, and said' invention is full-y disclosed in the following description and claims. y Referring to the said drawings, Figure 1 represents a portion of arailway-train, parts being shown in section, showing my improved apparatus installed therein. Fig. 2 represents a transverse sectional view, slightly enlarged, of a car-body, showing the location of thelongitudinal ventilating conduits or tub es. Fig. 3 is an enlarged longitudinal sectional view of a portion of one of the conduits, showing means for distributing air therefrom in either direction, according to the directionl of travel of the car. Fig. 4 is a view similar to Fig. 3, showing a slightly-modified construction. Fig. 5 is a view similar to Fig. 3, showing another modification. Fig. 6, Sheet 1, is an enlar ed detail view of the meeting ends of two a ined conduits of adjacent cars, showing the means for establishing connection from one to the other. Fig. 7 is a similar view showing the conduits connected. Fig. 8 isa longitudinal sectional view of Fig. 7 Fig. 9 is a transverse vertical section on line 9 9 of Fig. 7. Fig. 10 is a rear view of a car, showing it provided with' a slightlymodified form of apparatus 'for extending and 4 retracting the telescoping connecting tubes or sections. Fig. 1 1 isa perspective view of the apparatus for extending and retracting the telescoping tubes shown in Fig. 10. Fig. 12 is a side elevation of the same.

The object of my invention is to provide a train of cars with one or more (preferably two) lon itudinal ventilating-conduits exom the engine (at a point in advance of the smoke-stack) to the rear of the train, said conduits passing through the various cars of the train and being rovided, preferably adjacent to each seat, with a discharge-aperture having a suitable controlling device, so that fresh air can be supplie throughout the car and regulated as desired by the passengers thereof. It will be understood that the locomotive, which is not shown, will be provided with conduit-sections adapted to be connected with the conduit-sections of the cars and provided at their front ends with funnel-shaped orifices, which receive air as the train progresses, and the air is forced through the conduits and delivered in the various cars by the forward movement of the train.

In the drawings, C represents a car equipped with my improved ap aratus7 and as the apparatus is the same in a l the cars of the train a description of one will suffice for all. Each car is provided with two longitudinally-arranged air-conduits A A, preferably located at opposite sides of the car and above the seats, although they may be disposed in other positions, if desired. Each conduit is provided on its lower side with a plurality of enlarged portions a, which are preferably arranged so that one will be over each seat, although they may be Vso located that each will supply two adjacent seats, if preferred.

In Figs. 3, 4, and 5 I have shown several ways in which the fresh air may be dischargedinto the car. In Fig. 3 the enlarged portions a of the conduit-tube are each provided with two oppositely-inclined dischargepassages e a2, separated by a central partition c3, and a slide valve or plate a", mounted in suitable guides and capable of being moved horizontally to `close one or both of the outlet-passages. When the slide of* covers both openings, no air will escape at this point in the conduit. If it is desired to admit air to the car, the slide is moved so as to expose the end of the discharge-.passage nearest to the forward end of the car, so that the air will ow from the conduit through said passage and into the car, as in Fig. 3, the car being supposed to be moving leftward in said figure. The amount of air admitted may also be regulated by means of this slide, which can be made to partly or fully uncoverthe desired opening.

In some cases I prefer to discharge the air by means of a rotatingdevice, such as a fan, arranged in the conduit and operated by the force of the air-current flowing therethrough. Such a -construction is illustrated in Fig. 4;, in which A represents the air-con- IOO IIO

duit and a one of the enlarged portions thereof, in which a fan B is arranged on an axis b, disposed longitudinally of the conduit and supported in suitable bearings. In this instance the enlarged portion a5 of the conduit is provided with a single discharge-opening controlled by a slide or valve a". By opening this valve a portion of the air in the conduit will be forced out through the aperture by the fan B, which will be rotated by the air-current passing through the conduit, no matt'er in which direction the car is movgFig. 5 is a view similar to Fig. 4, showingl a conduit, here indicated as A2, having the enlarged portion a7, provided with a dischargeaperture controlled by a valve or slide as and containing a fan B', mounted on an axis b', extending transversely of the conduit` Each of the conduits A (or A A2) is provided adj acent to each end of the car with a valve, (indicated at A3,) so that the valve Aa at the rear of the rear car may be closed when a train is made up to prevent the escape of the air, and thus force the air forced in at the forward end of the train to escape into the cars. Each of the conduits A (or A A2) is provided at each end outside the car-body with means for establishing a connection with the corresponding conduit of the next adjacent car. I prefer to employ for this purpose the devices shown in Figs. 6, 7, S, and 9. The conduit is provided at each end with a slightly-flared portion A4, within which is located a sliding i flexible tubular section D, (see Figs. 7, 8, and 9,) preferably composed of rubber hose or tubing of any preferred type. This flexible inclosed sectlon is normally maintained in a retracted position, but is capable of being pushed out, so as to engage the flaring end of the next adjacent conduit and make a connection therewith, the exibility of these inclosed tubes permitting the ordinary movements of the cars without injury to the apparatus. Y

In the drawings I have shown the following means for projecting and retracting the flexible sections: Each conduit end is provided with a transversely-disposed shaft e,

carrying a toothed wheel e, the teeth of which project into the conduit through a suitable slot and engage a series of small holes in the bottom of the flexible section D, which thus form the equivalent of a rack` The shaft eis also provided at one side with a pinion e2, meshing with an intermediate pinion eX, which engages with a gear e3 on a stud secured to the conduit-wall and having an operating arm or lever E. This lever is ordinarily held in a rearward position, as

shown in Fig. 6 and at the left in Fig. 7, by a suitable spring e4, and each conduit end is also rovided with a segment or guide e5 for said ever and a hook or catch e to engage and lock the lever of the adjacent car.

When two cars are coupled together and it is desired to connect the opposed ends of their respective ventilating-conduits, one of the levers E is thrown forward, and. its end is placed under the hook a of the adjacent conduit. This projects the llexible connection D into the mouth of the adjacent conduit7 as shown in Figs. 7 and 8, and. places them in communication. When. the cars are disconnected, the lever E, which is in forward. position, will be drawn out of engagement with the catch e" as the cars separate, and the spring e* will draw back the lever and retract the flexible connecting-section D.

In Figs 10, 11, and 12 I have shown a slightly-modiiied form of apparatus for si-` multaneously extending and retracting the telescoping or sliding flexible connecting-` sections of both the ventilating-pipes, (where two pipes are e1nployed,) such apparatus being applied at each end of each car of the train. In these figures, F represents a shaft extending across the car and supported from the roof outside the body of the car by suitable hangers f. rihis shaft F carries two toothed wheels f', each of which engages one of the sliding flexible connecting-sections in the same manner as the toothed wheel e. in Fig. 8. f2 represents a ratchet-wheel secured to shaft F near its center, and G is a lever corresponding to the lever E, loosely mounted on shaft F and provided with a pawl g normally out of engagement with the ratchet-wheel f2, but capable of engaging and operating the same when the lever G is pulled down` The pawl g is provided with a cam-face gf, which engages a cam-face h on a retaining-pawl H, which is also adapted to engage the ratchetwheel. The construction of these pawls H and g is such that when the lever G is in its highest position, in which it is normallymaintained by a retracting-spring g2, the inclined or cam face g of said pawl gengages the camface 7L of pawl H and throws the pawl g out ofengagement with the ratchet-wheel f2, and the upper end of pawl g engages pawl H and also lifts it off of the ratchet-wheel, this entirely disengaging the latter from the pawls. The shaft F is provided with a torsional retracting-springfs, surrounding the same, one end being secured to the ratchet-wheel or to the shaft and the other end being secured to one of the bearings f, and this spring normally holds the connecting-sections D in their retracted positions. The lever G is also provided with a handle g3, depending therefrom to facilitate operating the same. The parts being in the positions shown in Fig. 11, if it is desired to extend the iiexible connecting-sections the operator grasps the handle g3 and draws down the lever G, thus placing both pawls g and H in engagement with the ratchet-wheel f2 as they fall into engagement therewith by gravity. The lever G can then be reciprocated to project the exroo'- IIO G is secured in aposition below its normal orv highest position by placing 1t 1n engagcmeiit with a hook I on the next car. r[.he levers Gr and hooksI o'l' adjacent cars are so arranged as to permit the -foregoing operation on either car. It the cars are drawn apart, the lever G will pull out from hook I and the spring g2 Will cause it to fly upward, carrying t ie pawl g into engagement with pawl II and simultaneously disengaging both pawls, when the spring f 3 will retract both of the extensible connecting-sections, as will be readily understood.
